When the pressure drop of the hydraulic system exceeds the range of Article 3.3.1, the hydraulic pressure device should be able to automatically start to replenish the pressure. Until the given working pressure value is reached. Check according to Article 2.7 of ZB/TG95011. After load operation, look at the pressure gauge reading and check the pressure compensation function. The value refers to the percentage of the working pressure. The quality characteristics of the pressure system. The pressure regulation range of the hydraulic system.
